BRAKE BOOSTER Brake Booster
The brake booster is a Lucas unit mounted on the
engine bay bulkhead with a 25.4mm diameter
master cylinder and integral brake fluid reservoir.
NOTE: The reservoir is also a combined
brake/clutch reservoir for manual transmission
vehicles.
Twin vacuum boosters of 8 inch and 9 inch sizes
are fitted.
The DSC booster is different having integral
pressure transducers and solenoids with air
control valves for the booster. The transducers are
located on the brake master cylinder and are used
for pressure feedback, brake application and fail
safe operation. The booster is used to supply
brake pressure without driver input.
ABS operation is no different to current Jaguar
vehicles.
Parking Brake
The parking brake lever is mounted on the RH
side of the centre console for all models, with
conventional button operation as current XJ
sedan. It is a self-adjusting system operating on
the rear brake callipers. All models have a leather
grip.

74The SCP communication network will remain
operational even with severing of one of the bus
wires. Communications will also continue if one
of the bus wires is shorted to ground or battery
positive voltage (B+), or if some , but not all,
termination resistors are lost.
Unlike the SCP communication network, the
ISO 9141 communication network will not
function if the wire is shorted to ground or battery
positive voltage (B+). Also, if one of the modules
on the ISO 9141 network loses power or shorts
internally, communication to that module will fail.
Control Modules
The vehicle control module functions are
described briefly below (for further information
refer to the relevant sections throughout the
Guide).
Anti Lock Brake/Traction Control and
Dynamic Stability Control, Control Modules
The anti-lock brake control module is connected
to the SCP communication network. The module
comes in two forms. The first type is the standard
equipped anti-lock brake system (ABS) with
traction control (TC). It controls the brake
pressure to the four wheels to keep the vehicle
under control while braking.
The second type of ABS is optional and is called
dynamic stability control (DSC). This control
module adds yaw sensors to the package to help
in sensing a loss of vehicle control.
Audio Control Unit
The audio control unit is connected to the SCP
communication network and also to the audio
control protocol (ACP) communication network.
The audio control unit communicates with the
compact disc and the cellular phone transceiver.
Driver Door Control Module (DDCM)
DDCM is connected to the SCP communication
network. The module controls many functions
including power windows, driver mirror, power
locks, and keyless remote entry.Driver Seat Control Module (DSCM)
The DSCM is connected to the SCP
communication network. The DSCM is located
under the driver seat and controls the seat
positions. The module also communicates with the
DDCM to control the driver seat memory
functions.

C. Off
D. Side (parking lamps)
E. Headlamps
F. Rear fog lamps
G. Front fog lamps (where fitted)
Autolamps Delayed Exit (A)
This feature leaves the headlamps turned on after
the ignition has been switched off, allowing the
driver and passengers increased visability on
leaving the vehicle. The switch has seven positions
and varies the time from three seconds up to
three minutes. After adjustment, the newly set
delay time will be displayed on the message
center.
Auto (B)
A light sensor on top of the instrument panel,
monitors exterior light levels and automatically
switches the side lamps and dipped headlamps on
or off. When light fades to the non-adjustable
preset level, the sidelamps and headlamps switch
on automatically. As light increases to the preset
level, the sidelights and headlamps switch off
automatically.Rear Fog Lamps (F)
Turn the switch to headlamps on, pull the switch
and then turn to position (F). Turning on the rear
fog lamps will also turn on the front headlamps.
Front Fog Lamps (G)
Pull the switch in positions (A), (B), (D) or (E) to
switch on the front fog lamps. Push to turn off. If
the rotary switch is turned off (C) the switch will
be retracted to its normal position and the fog
lamps will be turned off.
Daylight Running Lamps
In certain countries it is a legal requirement for
the lamps to be on during the hours of daylight.
With the rotary switch in the off position (C),
dipped headlamps, sidelights and tail and number
plate lamps will switch on automatically when the
ignition is turned to position II, the vehicle is out
of park (automatic transmission only) and the
parking brake is released.
Battery Saver
If the dipped or main beam headlamps are
switched on and the ignition is turned to OFF or
the key is removed, the lamps will automatically
turn OFF after 10 minutes. The sidelights will
remain ON.
Bulb Failure Monitoring
The tail and brake lamp bulbs are monitored for
failure and a corresponding message is shown in
the message center, e.g ÔLEFT TAIL LAMP FAILEDÕ.
There are two tail lamp bulbs in each tail lamp.
The message that a tail lamp has failed indicates
that both bulbs in that cluster have failed. The
message will be shown, even after a bulb is
replaced, until the next time the bulb is switched
on.
